The Seven Jewels of Chamar

Scattered, they flamed like distant suns, maddening the beholder. United, they became a godlike power for the glory of the Solar System. But, their flame lances still white-hot from killing, young Ormondy and the fabulous Firebird learned how impossible was the price of that power.
The bearded giant, Thymar Ormondy, raised stiffly on one arm from the bed of litter on the damp cave floor. He pointed the charred stub of his other arm at his son.
Beware the Firebird! His voice was distorted with pain. She'll kill a thousand men for every one of the Seven Jewels of Chamar.
Nathan Ormondy threw back his rain cape and knelt beside his dying father. The great hulk of the old man sank back upon the rags.
Did she do this? Nathan demanded fiercely. His eyes filled with flame at the sight of the terrible wound that had come from a shot in the back.
Thymar lay without answering. His eyes were closed. Nathan heard only the hushing sound of the eternal Venusian rains that blotted out the distant hills like a ragged curtain hung over the mouth of the cave.
Behind Nathan another shaggy spaceman touched his shoulder. It was Tabor, his father's companion. The two police custodians from Aquatown shifted uneasily.
Was it Firebird? Nathan demanded of the watchers.
Before they could answer, Thymar's remaining hand fell upon Nathan's wrist. There is more to tell, the old spaceman whispered.
Nathan hunched lower to seize every word. What is it?
The Jewels of Chamar—
Curse the Jewels of Chamar! They stink with blood. I'd blast them all if I could!
